Samba loses connection with domain

[Shawn McConnell!]

I have samba set up on an HP-Ux server it runs fine except once in a while I will get a message like this.

\\servername\ is not accessible. you might not have permission to use this network resource. Contact the administrator of this server to see if you have access permissions.
The security database on the server does not have a computer account for the workstation trust relationship.

Now what we have done in the past is the following.

1. Delete the server from active directory
2. Add the server back and be sure to check the
"Allow Pre-Windows 2000 computers to use this account" box.
3. Delete /var/opt/samba/private/secrets.tdb
4. net rpc join –w charlotte –S "servername" –U [-d 10]
“-d 10” is optional debug level

At times we have also just been able to run the net rpc join and that would clear up the problem.

Here is the smb.conf

# Samba config file created using SWAT

[adv_db]
path = /u01/app/advantage
valid users = @starteam

[scripts]
# path = /nfs/scripts
path = /u01/scripts
valid users = @starteam

[ums-files]
# default case = UPPER
path = /u01/ums-files
read only = yes
guest only = yes
guest ok = yes
browseable = yes

I don't have this issue with any of our linux servers.

here are the samba versions

CIFS-Client A.02.02 CIFS Client
CIFS-Development A.02.02.01 HP CIFS Server Source Code Files
CIFS-Server A.02.02.01 HP CIFS Server (Samba) File and Print Services


Any help would be great.

Thanks

Shalom Shawn,

Though for security reasons, I'd patch my HP-UX CIFS/Samba the cause is probably not your setup.

I would suspect the Windows Samba Server is the cause as I saw this behavior after a security patch to Windows a year or so ago.

Look there first.
